Well it all started in my CRX DX when a valve seal went bad draining oil out of the exhaust port. I pulled the head and I had an SI head laying around so I swapped that in instead of replacing the valve seals, probably a bad move. I kept my DPFI intake manifold on and at first idle was really high and little throttle response. Then I get an Injector code. Never had a problem with injectors before. I checked resistance both were fine, although one was leaking it looks to be coming from where the connector plugs in at. Tomorrow I will be replacing that whole injector. Anyone have some insight on this, maybe its overload because I'm not running four injectors like SIs are suppose to have I'm still running the PM5 DX ECU, the SI ecu wont even start the engine. I will probably be converting over to MPFI soon just don't have a resister box or SI wiring harness yet.
